GtkTargetEntry and GtkSelectionData

[Vikram Noel Ambrose <noel ambrose gmail com>]

I'm trying to understand how to pass data around from one treeview to 
another using the Drag-and-Drop mechanism.

For example, say both treeviews, have a list store of the following 
structure:

list_store = gtk_list_store_new(4,
               G_TYPE_STRING,G_TYPE_STRING,G_TYPE_INT,G_TYPE_FLOAT);

How do we define GtkTargetEntry for this sort of structure?

The manual says GtkTargetEntry.info allows you to identify the type of 
data. But where do you retrieve this information from in the 
"drag-data-received" signal of the destination treeview?

How do you supply all components (columns) of the list_store to 
gtk_selection_data_set()?. And consequently, how do you retrieve all 
columns from the "drag-data-received" callback?

In essence I'm trying to understand how GtkTargetEntry and 
GtkSelectionData are related.

Thanks,


Vikram.
